Duel with a Sage-level Demon King

In the end, Qin Chen still managed to rush back. He looked at the Sage-level Demon King in the sky, who was roaring at the sky. The latter's demonic aura was overflowing, and he frowned.

This shouldn't be the case. The seal he left behind should've been able to last for quite a while.

"Eh? It's you!" Naturally, the Sage-level Demon King also noticed Qin Chen. That familiar aura and familiar blood qi just felt so familiar that it couldn't help but reveal a surprised expression, "I wanted to find you. I didn't expect you to show up on your own. To think I didn't need to expend any effort."

"Elder King!?" The elders and disciples of the Taiyi Holy Land were all shocked. To think the Elder King had appeared at this time.

"Elder King, please leave immediately!" Ling Ran said in a hurry.

"Elder King, run!" The other elders and disciples also shouted for him to leave.
